So I am running 60 x 1070 in a garage. 10 Rigs buzzing away. The problem I have is that my house is a two storage and that my main bedroom is above my garage. So the vent of my rigs is just below my main bedroom window! Also, there is a door between my garage and my living room. So I had a reel problem with noise.
What helped a lot is getting low noise duct fans like this
http://a.co/d3GECHW. I got 6. You can also get silencers. I was planning on but turn out i did not need it. The 6 duct fans suck air from the rigs and blow it out a window via duct tubing.
Also what really helped is to make sure the rigs are low, close to the ground and that the duct fans take the air from the ceiling or the top rigs. I have two pillars of rigs with 5 rigs on each side. The top 2 rigs on a side air get sucked into the duct fans and the other two intakes are close to the ceiling.
Next problem I had was vibrations. I solved that by placing each rig on a rubber mat and the fans that push air through also on foam pads. I have fans pushing are thought the GPUs rigs all in the same direction.
What I did was a total overkill. I am running the duct fans at min power and the garage is never above +5c ambient. It is winter now so the out sid temp is 10-20c and my fans on the gpus are never above 50%. In summer it got over 30C outside and i never had a problem with heat in the garage
The rigs are open airframes and they are a bit wider than normal. so I have more space between the GPUs that really brings down the heat alot! All the cards are pointing to the windows with the duct fans sucking on that side.
I have a 160w extractor fan that is ready hanging in front to the window but, I don't need it any more sins I got the duct fans.

Old photo of setup. The top rig is no longer there. It is now on the right hand side.
I hope this helps.
